Symphyotrichum eulae (formerly Aster eulae) is a species of flowering plant in the family Asteraceae endemic to north-central Texas. Commonly known as Eula's aster or Texas aster, it is a perennial, herbaceous plant that may reach heights between 5 centimeters (2 inches) and 1.5 meters (5 feet). Usually, its flowers have white to bluish or lavender-white ray florets and yellow then reddish to brown disk florets. It is named for Eula Whitehouse, American botanist, botanical illustrator, and plant collector.

Description

S. eulae is a perennial, herbaceous plant that may reach heights between 5 cm (2 in) and 1.5 m (5 ft). It grows from a long and thick rhizome and forms colonies of plants that each have one to three or more erect, straight, and stout glabrous (hairless) stems.^[6]

Leaves

Flowers

Involucres and phyllaries

Florets

Usually, its flowers have white to bluish or lavender-white ray florets and yellow then reddish to brown disk florets.^[6]

Fruit

Chromosomes

S. eulae has a monoploid number (also called base number) of eight chromosomes (x = 8). The species is hexaploid with six sets of the chromosomes for a total chromosome count of 48.^[6]

Taxonomy

Classification

Symphyotrichum eulae is classified in the subgenus Symphyotrichum, section Symphyotrichum, subsection Dumosi.^[7] It is one of the "bushy asters and relatives."^[8] Its basionym (original scientific name) is Aster eulae,^[9] and its name with author citations is Symphyotrichum eulae (Shinners) G.L.Nesom.^[2] Botanist Lloyd Herbert Shinners described the species in 1950, classifying it within the genus Aster.^[10]^[11]

Conservation

As of January 2023^[update], NatureServe listed Symphyotrichum eulae as Apparently Secure (G4) globally and the same (S4) in Texas. Data was provided by the Texas Parks and Wildlife Department Wildlife Diversity Branch. The global status of S. eulae was last reviewed by NatureServe on 1 February 1994.^[1]

Uses

Shinners reported "also in cultivation"^[12]

Notes

^ This is a county map of east central Texas showing the range of S. eulae as described by Lloyd Herbert Shinners. Darker green shaded counties were in Shinners' 1950 protologue of Aster eulae. Lighter green shaded counties are within the area covered by Shinners' description. Darker green counties are, alphabetically, as follows: Bexar, Calhoun, Cooke, Dallas, Denton, Hill, Hunt, Kaufman, Navarro, Rockwall, Tarrant, Wise, and Wood.^[3] The following counties are shaded lighter green because they are within Shinners' range but are not specifically named by him: Anderson, Austin, Bastrop, Bell, Bosque, Brazos, Burleson, Caldwell, Collin, Colorado, Comal, Coryell, DeWitt, Ellis, Falls, Fayette, Freestone, Goliad, Gonzales, Guadalupe, Hays, Henderson, Hood, Jack, Johnson, Karnes, Lavaca, Lee, Leon, Limestone, Madison, McLennan, Milam, Parker, Rains, Robertson, Smith, Somervell, Travis, Van Zandt, Victoria, Waller, Washington, Williamson, and Wilson.^[5] Only McLennan County is green on the S. eulae page in the USDA PLANTS database.^[4]
